Not truly new information

Not truly new information but due to many misunderstandings, we would
like to take this opportunity to address once more the issue of our
exclusively used material.

All of our sports and play equipment is made from polymer concrete
(previously: acrylic concrete). The terms mineral composites, molded
mineral, and cast minerals are sometime used synonymously. To simply use
the term concrete is incorrect. Concrete alone usually
describes the different types of cement concrete. Cement concrete is
porous and absorbs water. This means it deteriorates over time due to
weathering; penetrating water freezes and the upper layer of the
concrete flakes off. (By the way, this also happens with concrete
advertised as "weatherproof"...)
